Thanks for the reply. I really don't want to capture how to do the
extraction; we have registries for formats and tools to store that
information so that we are not locked into a specific tool and syntax.

with the zip or tar file. This is more like an offset within a media
file. I'm talking with John Kunze about whether we can do this with
the qualifier portion of an ark identifier. If that works, this
becomes a simple xlink:href.
Thanks --- Evan

attribute to record a string description, or 2. use the
TRANSFORMBEHAVIOR to reference a specific <behavior> element which
implements the transformation. If you're using option 1, you might
